Ni-Cr Now Cheaper Than Steel On Unit Power Basis
Ni-Cr Now Cheaper Than Steel On Unit Power Basis
(OP)
Someone recently complained about the high cost of the materials used in gas turbines. Until recently this was true on both a unit power basis as well as a unit weight basis.
Now with steel trading at $400/ton and comparing the cost of Ni-Cr alloy in a large turbofan to the steel in a vehicle reciprocating engine, the Ni-Cr comes out cheaper than steel on a unit power basis.
Other considerations like cost of labor are more important than cost of materials.

Unless I'm misunderstanding something, which is always a good possiblity.

Signs have been popping up "will remove your junker for free." It will be interesting to see if they clean out those cars that ran off the road/cliff and into the canyon.

In the last 18 months Mo has gone from $3/lb to $40/lb
Base prices for SS have only gone up about 25%, but the surcharges have gone sky high.
Trust me, today 439 looks like a good option to replace light gage 304 for low temp applications. And the superferritic grades are a lot less expensive than Ti and 6%Mo superaustenitic grades.
If you are working with prices more than a few weeks old you need to check again.

Mo +300% (always compared to end 2003)
Ni -6%
Cr (high C) +20%
Cr (low C) +37%
Mn +26%
We have the impression that steel scrap for one is over its top. We're getting quotes now for 300-310EUR/metric ton. A few weeks ago this was still over 400EUR/metric ton.
Rumours go that Mo will drop sharply in the comming weeks.
Any comments?

Mo looks firm for the next few months. I don't expect to see it drop until mid-summer. By the end of the year I expect Mo to be $10.
Ni looks like it will hold in the $6-7 range.
Cr will give back a little, but stay strong.
Now I can put the crystal ball away.
